TITLE : Unit 11: Blood, Lymphatic System, and Immunity SUGGESTED DURATION : 10 days

Unit Overview

During this Unit

This unit bundles student expectations that address the interrelationship of blood, the lymphatic system, and the immune system in maintaining a healthy internal environment. Students determine the effects of pH imbalances, environmental factors and genetics on blood components, and the resulting consequences to the body.

 

Streamlining Note

In Biology TEKS B.4A, students now compare and contrast scientific explanations for cellular complexity in addition to previous expectations. The former Biology TEKS B.11A, describe the role of internal feedback mechanisms, was removed during the streamlining process implemented in 2018-2019. Students continue to understand the concept of process regulation in animals in the context of TEKS B.10A, and homeostasis at the cellular level is addressed in TEKS B.4B.

 

Prior Content Connections

  • Biology
    • B.4 – The student knows that cells are the basic structures of all living things with specialized parts that perform specific functions and that viruses are different from cells. The student is expected to:
      • B.4A – Compare and contrast prokaryotic and eukaryotic cells, including their complexity, and compare and contrast scientific explanations for cellular complexity.
      • B.4B – Investigate and explain cellular processes, including homeostasis and transport of molecules.
    • B.10 –  The student knows that biological systems are composed of multiple levels. The student is expected to:
      • B.10A – Describe the interactions that occur among systems that perform the functions of regulation, nutrient absorption, reproduction, and defense from injury or illness in animals.
      • B.10C – Analyze the levels of organization in biological systems and relate the levels to each other and to the whole system.  
    • B.11 – The student knows that biological systems work to achieve and maintain balance.                                                               

 

After this Unit

Students will enhance their understanding of blood, the cardiovascular system, and the importance of transport system interrelationships.

 

According to Research

“By the end of the 12th grade, students should know that:

  • The immune system functions to protect against microscopic organisms and foreign substances that enter from outside the body and against some cancer cells that arise within.
  • Communication between cells is required to coordinate their diverse activities. Cells may secrete molecules that spread locally to nearby cells or that are carried in the bloodstream to cells throughout the body. Nerve cells transmit electrochemical signals that carry information much more rapidly than is possible by diffusion or blood flow.
  • The human body is a complex system of cells, most of which are grouped into organ systems that have specialized functions. These systems can best be understood in terms of the essential functions they serve for the organism: deriving energy from food, protection against injury, internal coordination, and reproduction.
  • Some allergic reactions are caused by the body's immune responses to usually harmless environmental substances. Sometimes the immune system may attack some of the body's own cells.
  • New medical techniques, efficient health care delivery systems, improved diet and sanitation, and a fuller understanding of the nature of health and disease give today's human beings a better chance of staying healthy than their ancestors had.
  • Some drugs mimic or block the molecules involved in communication between cells and therefore affect operations of the brain and body.
